ROTARY CAR DUMP Filed Dec. 15. 1928 4 Sheets-Sheet 4 INVENTOR WITNESS: ATTORNEY V i atented Nov. 12, 1929 general object of the invention being to pro-' COMPANY, OF BOWEBSTON, OHIO I ROTARY one ew Application filed December 15, 1928; Serial, No. 326,228.- I

This invention relates to a rotary dump mainly designed for dumping mine cars, the

vide a supporting structure provided with a rim at each end thereof, and two pairs of wheels which are engaged by the rims,one pair of wheels arranged at one side of the apparatus being connected to a drive shaft with means for holding the rims out of engagement with the drive wheels when the structure is 1n normal or unloading posit on and means asso ciated with one of the drive wheels for giving the structure an initial movement whereby its rims will engage the drive wheels and the structure will be given a complete revolution.

7 Another object of the invention is to provide stop means for holdingthe structure in its normal or non-dumping position with its rims out of engagement with the drive wheels, with single means for moving the stop means to releasing position and giving the structure its initial movement. 7 I

This invention also consists in certain other features of construction and in the combination and arrangement of'the several parts,

to be hereinafter fully described, illustrated in the accompanying drawings and specifi cally pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein the characters denote like or corresponding parts throughout the several a i stop means in releasing position and the structure ready to be given its initial movement. Figure 4 is an end view showing the parts with the structure in dumping position.

Figure 5 is a similar view showing the structure just before it completes its rotary movement.

Figure 6 is an enlarged sectional view showing the clutch assembly and the front endof the drive shaft.

In these views 1 indicates the frame or structure for. supporting the mine carA structure having the rims 2 at its ends. *A-

pair of shafts 3 andi are supported on abase 5 and the shaft 3 has a pair offlangedwheels 6 looselymounted thereon while the} loosely mounted on the-shaft and each larger wheel is placed adjacent the outer face of the plain wheel. The rims 2 rest'upon the wheels 6 and the wheels and 7 but when 7 the structure or frame 1 is in normal or, nondumping position recesses 9 formed in the rims 2wi11 be opposite'the wheels?v and 7 with shoes 10 passing through the rimsad-j a- This shaft 4: alsocarries rice A GLEIQTN 'w.

Thus The wheel 8 has a plurality of pins 14;

passing through the same, a grooved collar 15 being fastened to the outer endsof these pins and a clutch part 16 being fixed to the in-.

ner end. This'clutch part is adapted to engage aclutch face 17 on the wheel 7 when the clutch part is, moved towards the wheel .7." 3 thereby connectingsaid wheel 8 withpthe 1 wheel7 so that said wheel Swill rotate with c the wheel 7 and the shaft, .As the said wheel;

8 is'in engagement with one of thefshoes. lO'this movementof the wheel 8=will.b;e1 imparted to the frame 1, throughnmeansg of said shoe 10 so that the frame is given its initial movement! This initial movement of the structure will cause the recessed portions of the rims to move away from the wheels 7 and 7 so that the rim Swill. engage these wheels and as these wheels are; attached to the constantly driven shaft the. rims and the frame lwill begiven a rotary.

movement so that the car will be dumpedand returned to upright position. r

7 place its rims in engagement with the wheels.

A lever 18 is connected by the link 19 with the clutch fork 20 and by the link 21 with the arm 22 on the shaft 12, so that when the lever is manipulated the clutch will be moved into engagement with the Wheel 7 and at the same time the; shaft 12 will be rocked to move the stop 11 out ofthe path of the shoe 10, thus moving the stop to operative position and giving the-structureits initial movement at the same time. After the rims are in-engagement with the wheels 7 and 7 thelever is moved back to its normal position sou-as to place the stop in position to engage the shoe 10, after the structure has made a complete revolution and to release the Wheel 8 from the Wheel 7. r It will be, of course, understood that the frame 1 is provided with track'23 which is in'alinement with the track 24 when the frame in normal or non-dumping position so that'a car can pass from the track 24; upon the traclr- 23. Flanges 25 are arranged on the frame and on the car to hold the car in place during the dumping operation and'a deflector plate 26 is arranged adjacent one side of the-frame for deflecting the material from the car to a point underthe device.

In order to prevent the wheel 8 from slipping on the shoe when the wheel is given its initial movement I provide the shoe with a pointed projection27 which is engaged by pins 28 on the wheel so that as a pin'strikes a projection it will cause the shoe and, therefore, the rim, to move with the wheel. The

pins are slightly pointed as shown so that there is no danger of the projection riding onthe pin if the two should strike each otheras: they cometogether. If this should occur the pointed part of the projection strike ing the pointed part of the pin would cause the parts to slip off of each other, this being permitted due to the fact that the wheel Sis free to move.

From the foregoing it will be seen that I" have providedmeans whereby the drive shaft can be constantly rotated such as by a'motor' M "without imparting its .movementto the car supporting structure but as soon as the clutch is thrown into action and the stop ture is given its initial movement which will fastened to the drive shaft and thus the movestructure. 1 r r H It is thought from the foregoing description that the advantages and novel features of my invention will be readilyapparent.

I" desire" it to be understood that I may combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

Having describedthe invention, I claim:
